1-1/8 & 1-1/4 front sway bar vs factory 7/8?

Ok, I know I'm a day late and a dollar short, you obviously went with the Hellwig setup. But I said I'd report back on my
Hotchkis sway bar install. Night and Day difference from my stock 7/8" bar. Car feels great, predictable, and virtually no body roll in corners.
Went for a 5 min test drive, and the car felt so great I just didnt want to stop driving, got home 35 minutes later with a big smile of my face.

The hotchkis bar is 1-1/2" hollow. The mounts that came with look a lot like yours, but they have you weld them onto the K-frame.
Good luck with your new setup!

Only reason i went the hellwig route is cause i didnt want to permanetely weld the brakets to the k member, otherwise i would of went the hotchkis route, glad it worked out for you!
